Patent number: 11001761Abstract: A method and a composition for treating tailings from a separation process are disclosed, where bitumen is separated from mineral solids. Tailings include an aqueous phase with suspended solid particulate material and residual bitumen and have a dry solids content <25 weight-%. The method includes addition of a flocculating agent including polyacrylamide to the tailings, as well as addition of an auxiliary agent including ionic liquid to tailings in conjunction with the flocculating agent. Flocs, which include solid particulate material, are formed and the formed flocs are separated from the aqueous phase. The composition in a copolymer of (meth)acrylamide and an auxiliary agent comprising ionic liquid.Type: GrantFiled: December 7, 2017Date of Patent: May 11, 2021Assignee: Kemira OyjInventors: Thomas Fenderson, Lasse Kyllönen, Alistair King, Evangelos Sklavounos, Frances Fournier, Sukhjit Aujla

Patent number: 10726981Abstract: The present disclosure relates to a method for manufacturing a covalently functionalized coated magnetic nanoparticle and to said particles and uses thereof. The preparation method includes forming a shell of a hydrophilic polymer coating layer on top of a magnetic metal core coated with a carbon coating. In the method a particle comprising a magnetic metal core coated with a carbon coating is provided. The surface of the particle is subjected to covalent functionalization by generating amino reactive groups via diazonium chemistry and subsequently an irreversible attachment of an atom transfer radical polymerization (ATRP) initiator is carried out on said surface. A hydrophilic polymer layer is formed) by a surface initiated atom transfer radical polymerization (SI-ATRP) reaction with a monomer comprising N-isopropylacrylamide (NIPAM).Type: GrantFiled: September 21, 2016Date of Patent: July 28, 2020Assignee: Kemira OyjInventors: Mehrdad Hesampour, Lasse Kyllönen, Ari Auvinen, Adina Anghelescu-Hakala

Patent number: 10081689Abstract: The invention relates to a method for preparing a dry cationic hydrogel polymer product. The method comprises polymerization of a reaction mixture comprising ethylenically unsaturated monomers in presence of water and initiator(s) by radical polymerization and obtaining a hydrogel polymer. The hydrogel polymer is comminuted by chopping or shredding, and dried, whereby a dry hydrogel polymer product in powder form is obtained. At least one cationic reverse phase emulsion polymer is added to the hydro polymer at the comminuting step. The invention relates also to a dry cationic hydrogel polymer composition prepared by the method and its use.Type: GrantFiled: November 17, 2015Date of Patent: September 25, 2018Assignee: Kemira OyjInventors: Ronald Van Rossum, Susanna Holappa, Lasse Kyllönen
